  • Patent number: 4161817
    Abstract: A method of fabricating a semiconductor device mounting element embodying a wire fan-out wherein the ends of a plurality of insulated wires are supported in a spatial parallel arrangement of columns and rows between two spaced apertured die elements, the spacing of the wires is reduced at a first location between the die elements while maintaining the spatial arrangement of columns and rows, forming an enclosure about the wire portions positioned adjacent one of the die elements and the location where the spacing of the wires is reduced, injecting an organic hardenable resin material into the enclosure thereby encapsulating the wires positioned within, severing the wires, and removing the die.
